CBI Director Amar Pratap Singh today relinquished the charge of the probe agency after a two-year-long tenure during which he supervised some of the most high profile graft and crime cases including the 2G scam.

60-year-old Singh had taken charge of the agency at a time when some big-ticket corruption cases like telecom spectrum allocation scam and CWG scam were in media glare.

Singh, an IPS officer of 1974-batch Jharkhand cadre, steered the agency through complex investigations and in the process ensured that the Supreme Court set deadlines are met.

During his tenure, he took some out of the box steps like taking help of the FBI in identifying charred bones in Bhanwari Devi murder case.

Singh will be succeeded by his batchmate from Bihar cadre and senior IPS officer Ranjit
Sinha, who is likely to take charge of the agency on Monday.

An avid golfer, Singh wishes to devote time to sports and travelling, which he could not pursue during his tenure as the chief of the central agency.

Singh was the 24th Director of CBI after its formation in 1963 and took over as Director, CBI on November 30 last year.

He had held several important positions in CBI including that of Special Director from April, 2009 to November, 2010 besides the post of DIG and SP in CBI from 1987 to 1995.

Several steps for modernisation of CBI were also taken during his tenure which included modernisation of CFSL among others.
